Restorative dentistry involves crowns and bridges. Crowns are used to restore a single damaged tooth, while bridges are used to replace one or more teeth. Crowns and bridges can both restore form and function to your teeth.
When your dentist talks to you about using a crown, he is talking about a procedure that restores a single tooth that is so damaged that no longer can hold a filling. For example, your tooth may be so decayed, cracked, or in danger of cracking that it needs the support and strengthening of an individual crown.
The finished crown that the dentist secures to your existing tooth looks and functions the same as a natural tooth. It covers the tooth completely, fitting onto the gum and protects your tooth from further damage.
Missing teeth are not just an appearance issue. They can also lead to serious complications in your mouth. One or more gaps in your teeth can allow your remaining teeth to shift out of position. These shifts can lead to a change in your bite, loss of additional teeth, tooth decay, gum disease, as well as migraine headaches.
If you are missing teeth, your dentist may suggest dental bridgework. A bridge is a group of interconnecting crowns. It stabilizes your bite if you are missing one or more teeth, prevents further damage to your teeth and gums.
